问题描述
对于给定的文件，说我从 / main / 2 分支出来，然后在该分支中进行开发。 newBranch 。 cleartool diff -pred 会将我加载的版本（ / main / newBranch / LATEST ）与进行比较/ main / 2 。我将通过哪个clearcase命令传递文件名或 / main / newBranch 并返回 / main / 2 ？
For a given file, say I branched off from /main/2 and do my development in that branch newBranch. cleartool diff -pred would compare my loaded version (/main/newBranch/LATEST) to /main/2. Which clearcase command would I pass either the file name or /main/newBranch and would return /main/2?
我只是想找到 -pred 选择哪个版本，但是我找不到任何地方！
I'm just trying to find which version -pred selects, but I can't find out how anywhere!
跟进：
说我签入了文件，现在我的版本是 / main / newBranch / 3 。我如何仍可以将其与（ / main / 2 ）的分支进行比较？
FOLLOW UP:Say I checked the file in and now I'm in version /main/newBranch/3. How can I still compare it to where it was branched off from (/main/2)?
推荐答案
我将使用哪个ClearCase命令传递文件名或 / main / newBranch 并返回 / main / 2 ？
Which ClearCase command would I pass either the file name or /main/newBranch and would return /main/2?
您可以尝试使用，它将列出文件的所有版本。
You can try using cleartool lsvtree, which will list all versions of a file.
cleartool lsvtree myFile | grep main | head 1
如前所述，更容易。
As noted, cleartool describe is easier.
您可以使用 / main / newBranch / 0 ， 0 作为，此处与 / main / 2 ，使用：
You can use the /main/newBranch/0, 0 being the placeholder version created for each new branch, here identical to /main/2, using cleartool diff:
cleartool diff -pred yourFile yourFile@@/main/newBranch/0
